Subsea7 has contracted Corinth Pipeworks to manufacture steel pipes for two field developments in the North Sea.
The OKEA-operated Bestla project is a 13-km two-well subsea tieback to the Brage field platform to the north.
Corinth will supply 12.5 km of 14-inch, High-Frequency Welded (HFW) steel pipes.
In the UK central North Sea, the Bittern project calls for the manufacture of about 22 km of HFW steel pipes for a 12-inch water injection pipeline, 190 km east of Aberdeen.
It will replace the existing line to maintain reservoir pressure support for the remaining life of the Bittern field. Subsea7 will install the lined pipeline next year, along with subsea structures and tie-ins at both Bittern and the host Triton FPSO.
For both contracts, Corinth Pipeworks will apply an external coating at the same pipe manufacturing site.
The company’s facility is equipped to provide this service to 22.9-m-long steel pipes.
